my major concern is that we get fixed on the idea that technology is the only answer to our military challenges, that we are only going to fight certain kinds of wars in the future. you know, we say we would never fight another counterinsurgency after vietnam but guess what, we did, and as i look back at all of the times we have used military force since vietnam, when it comes to predicting where we will use our military next, we have a perfect record. >> rose: we are always wrong. >> i have never gotten it right, not once. >> rose: why? >> because the world is unpredictable. and so my mantra when i was secretary was, we need a force that is equipped and trained to provide the maximum possible versatility across the broadest possible range of conflict, because we can't predict what the next conflict will be like and, therefore, we have to train and have as much flexibility and versatility as possible. we can't just prepare for one kind of conflict. > >> rose: you also have said, i think on leaving, that i don't want to be secretary of state when you are fighting these kind of ground
